“My happiness is indescribable!” Keibler, 34, tells PEOPLE. “Marriage is the ultimate bond of love and friendship. It means putting all your faith and trust into a person that you can’t help but believe is your soul mate. Someone who has all of your best interests at heart; someone handpicked for you, to help you grow and be the best person that you can be. Jared is all of this for me.”

The couple, who began dating last fall, wed in an intimate ceremony in Mexico.
